Definitions

  • the invention relates to a reader for a chip card
  • An electronic writing and reading device having at least one antenna for contactless reading of data stored on the chip card and for contactless writing to the chip card with data by means of electromagnetic waves generated by the antenna and with
  • a front recess provided for receiving the chip card with a height which corresponds to a multiple of the thickness of the chip card, - the antenna being arranged in such a way that its electromagnetic waves are fed into the recess.
  • Such a reading device is known from the Siemens brochure “SecureContectless TM Electronic Ticketing, The Check-in / Check-out Terminal *.
  • This previously known reading device has a pocket-shaped recess on the front for receiving the chip card.
  • the antenna of the reader is arranged in such a way that its electromagnetic waves are fed into the recess.
  • the function of the recess is that the user of the reader is very effectively protected from the electromagnetic waves or the radiation from the antenna of the reader by the recess, because the previously known reader has a kind of shielded reading space due to the blind hole-shaped recess on the front , into which the card is easy to insert due to the generously dimensioned height of the recess for reading or writing.
  • the electromagnetic waves of the antenna are only radiated into this reading room and are therefore, so to speak, trapped in this reading room, so that a Radiation of the electromagnetic waves perpendicular to the front in the direction of the user of the reader is almost completely avoided. For this reason, an unintentional reading or writing of the chip card is almost impossible in the known reader, since the chip card must always be inserted into the recess for reading or writing; An unintentional reading or writing of the chip card, which the user only happens to carry with him, is therefore not possible.
  • A19100-V200-B705-X-7600 from Siemens and Cubic. All of these devices have in common that signals are sent in the form of electromagnetic waves to the chip card to be read or written or signals sent by the chip card are received by means of an antenna mounted in the area of the front plate of the reading device; the antenna is attached to the known devices such that the electromagnetic waves are emitted perpendicular to the front plane in the direction of the user of the reader.
  • the chip card is therefore for reading and
  • the invention is based on the object of specifying a reading device which enables secure reading and writing of chip cards even at particularly low transmission powers of the antenna. This object is achieved according to the invention in a reader of the type mentioned at the outset in that the antenna is attached in the region of a side wall of the recess.
  • the main advantage of the reading device according to the invention is that by arranging the antenna on a side wall of the recess, it can be operated very reliably even with very little antenna transmission power, because the electromagnetic waves generated by the antenna “fill” the recess very evenly, so that a secure reading and writing of chip cards is possible even with low transmission power.
  • the antenna is attached in such a way that the main beam axis of its main beam lobe lies approximately parallel to the opening area of the recess.
  • Particularly suitable antennas for reading devices are, for example, loop antennas, so that it is considered advantageous if the antenna is a loop antenna.
  • the frame antenna can be rectangular or round, for example.
  • the recess can be filled particularly uniformly with the electromagnetic waves of the antenna if the dimensions of the loop antenna are adapted to the dimensions of the recess.
  • the user of the reading device can be protected particularly reliably against the electromagnetic radiation of the antenna if the recess forms a blind hole because then particularly little transmission power of the antenna can escape to the outside.
  • the figure shows a reading device 5 for a chip card 10.
  • the reading device has an electronic writing and reading device 15 for contactless reading of data stored on the chip card 10 and for contactless writing to the chip card 10 with data.
  • the writing and reading device 15 is equipped with an antenna 20. Electromagnetic waves generated by the antenna 20 are identified in the figure by an emission lobe 25, which at the same time represents the radiation characteristic of the antenna 20.
  • the reader 5 has a blind hole-shaped recess 35 on a front side 30, into which the chip card 10 is inserted for reading and writing.
  • the electromagnetic waves of the antenna 20 are fed into the pocket-shaped recess 35; this can be seen from the figure by the position of the main beam 25 of the antenna 20. It can also be seen in the figure that the antenna is attached in such a way that the main beam axis 36 of the main beam lobe 25 is largely parallel to the opening area of the recess.
  • the antenna 20 is arranged on a side wall 40 of the pocket-shaped recess 35 such that the electromagnetic waves or the radiation from the antenna 20 are directed into the interior of the recess 35.
  • the antenna 20 alone is sufficient for the functioning of the reading device.
  • the antennas 20 and 20 ' can be, for example, loop antennas, the dimensions of which are adapted to the dimensions of the pocket-shaped recess 35; the frame antennas can be formed, for example, by conductor loops.
  • the writing and reading device 15 is equipped with a power supply device 50, control electronics 55 and an LCD display 60 with which the task information of the reading device 5 can be output to the user of the reading device 5.
  • the blind hole-shaped recess 35 is dimensioned at its opening in the direction indicated by a double arrow 65 so that the chip card 10 can only be inserted into a recess 35 in the position shown in the figure and not rotated by 90 ° around its longitudinal axis. Even with the flat side, the chip card 10 cannot be inserted into the recess 35.

Abstract

L'invention concerne un lecteur (5) pour carte à puce (10), comportant un dispositif d'écriture et de lecture (20) électronique présentant au moins une antenne (20), qui permet d'extraire sans contact des données mémorisées sur la carte à puce (10) et d'inscrire sans contact des données sur ladite carte à puce(10) à l'aide d'ondes électromagnétiques (25) produites par l'antenne (20). Ce lecteur comporte également une cavité (35) située à l'avant et prévue pour recevoir la carte à puce (10), dont la hauteur correspond à un multiple de l'épaisseur de la carte à puce (10). L'antenne (20) est disposée de manière que les ondes électromagnétiques (25) qu'elle produit soient injectées dans la cavité (35). Afin de permettre, pour ce type de lecteur, y compris dans le cas où la puissance d'émission de l'antenne est particulièrement faible, d'extraire de manière fiable des données de cartes à puce et de les y introduire, il est prévu selon l'invention de monter l'antenne (20) dans la zone d'une paroi latérale (40) de la cavité (35).
